Vaal Temple Energy Crystals only spawning 1 instead of 2 on 6-mod T15 maps

I am reporting an issue where 6-mod Tier 15 Vaal Temple maps are only spawning 1 Energy Crystal instead of the expected 2.

I have run 16 maps so far, and in every instance, only one crystal was generated. Please investigate this as soon as possible.

same here. Its not always but it happens

IT also happens with 8 mod maps, you get 2 instead of 3
